How is h. pylori usually diagnosed?
I have chronic coughing from acid reflux. Since two other household members got it at the same time, the ENT doctor suspects it is caused by h. pylori infection of the stomach, so he referred me to a GI doctor.
I read there are three ways of diagnosing h. pylori. Breath test, blood test, and endoscopy. Which one is usually used? Is it usually done on the first visit or is it scheduled at another time?
Right now, I'm on 40 mg of prilosec twice a day which only helps somewhat. Do I have to get off prilosec since I heard it affects the test and may give me a false negative?
